Pilgrimage has the power to change the world and we're only just beginning to understand its potential. One aspect of this is pilgrimage as a peace-building initiative: an act that can help span cultural and religious divides and promote reconciliation. Dr. Ian McIntosh is part of a growing body of researchers studying this phenomenon, and he documents his experiences and insights in his book, Pilgrimage: Walking to Peace, Walking for Change. In this episode, Ian takes us around the world on a quick survey of some of the places where this potential is on display.
